Question 1191855
<br>
Given:
iron:nickel = 21:5
nickel:copper = 4:3<br>
Write each ratio as an equivalent ratio so that the numbers representing nickel in both ratios are the same.<br>
iron:nickel = 84:20
nickel:copper = 20:15<br>
Then
iron = 84x
nickel = 20x
copper = 15x<br>
The total is to be 238g:<br>
84x+20x+15x = 238
119x = 238
x=2<br>
ANSWERS:
iron = 84x = 168g
nickel = 20x = 40g
copper = 15x = 30g<br>
